The National Ground Water Association is offering the course, “Borehole Geophysical Logging for Water Resources/Water Supply Applications,” April 11-13 in San Jose, California. The objective of this course is to provide a basic framework and criteria for the use of borehole geophysics (wireline logs) in the design or rehabilitation/abandonment of resource/water supply wells. ...

Digital borehole geophysical logs and related data files are now accessible through GeoLog Locator, a new web-based map view and retrieval tool developed by the U.S. Geological Survey. The tool releases more than 7000 digital borehole geophysical logs at more than 1700 locations to the public — many for the first time. Hydrogeologists, ...

We have uploaded the technical specs of our borehole cameras range. In cooperation with MPI,we retail and support the following range of products: Underwater camera video systems for viewing water wells and vertical and horizontal boreholes Finding ground water pollution and ground water contamination inflows into wells Inspection camera systems ...

This guide applies to commonly used surface geophysical methods for those applications listed in Table 1. The rating system used in Table 1 is based upon the ability of each method to produce results under average field conditions when compared to other methods applied to the same application. An “A” rating implies a preferred method and a “B” rating implies an alternate ...

This guide summarizes the equipment, field procedures, and interpretation methods used for the determination of the depth, thickness and the seismic velocity of subsurface soil and rock or engineered materials, using the seismic refraction method. Measurement of subsurface conditions by the seismic refraction method requires a seismic energy source, trigger cable (or radio link), geophones, ...

The U.S. Department of Energy (DOE) announced the selection of 13 projects to develop technologies and methodologies for geologic storage of carbon dioxide (CO2). Carbon capture and storage (CCS) research is focused on developing technologies to capture industrially generated CO2, and safely and permanently store it in underground geologic formations, in order to reduce the amount of CO2 being ...
